1. Investigating the Dependence of Angle of Deviation on Angle of Incidence Using a Hollow Prism Filled with Different Transparent Fluids Zala yagnik

2. Introduction What is the angle of deviation? - Importance of studying light refraction through different media.

3. Objective To determine the relationship between the angle of incidence and the angle of deviation for a hollow prism filled with various fluids.

4. Materials - Hollow prism - Laser or light source - Protractor and ruler - Fluids (e.g., water, glycerin, ethanol, etc.) - Angle-measuring device - Graphing tools

5. Theory - Refraction of light (Snell’s Law). - Definition of angles of incidence, refraction, and deviation. - How the refractive index of fluids affects deviation.

6. Experimental Setup Labeled diagram showing: - Light source - Hollow prism - Path of refracted rays.

7. Procedure 1. Fill the prism with a chosen fluid. 2. Direct a light beam at varying angles of incidence. 3. Measure the angle of deviation for each angle of incidence. 4. Repeat with different fluids.

8. Data Collection Record data in a table: - Fluid type - Angle of incidence - Corresponding angle of deviation.

9. Observations Describe trends observed during the experiment. - Note any anomalies or unexpected results.

10. Graphs Graph showing: - Angle of incidence vs. Angle of deviation for each fluid. - Compare the slopes/trends of different fluids.

11. Analysis Interpretation of the graphs. - Explain how the refractive index affects the deviation angle.

12. Results Key findings summarized: - Highlight any significant differences between fluids.

13. Sources of Error Possible errors: - Misalignment of prism - Impurities in fluids - Measurement inaccuracies.

14. Conclusion Restate the objective and main findings. - Conclude on the relationship between incidence and deviation angles.
